Hogwarts: I rely on MC to pretend to be an alchemy professor

"Professor, let's just say, is this thing really safe?"

Neville looked at Kaisen lying on the stone slab on the magic infusion table, and the surrounding display tables were filled with wind-attributed crystal fragments.

The cube floating in the air was still turning quietly there.

"Don't worry, I did a lot of rituals to improve stability this time, there will be absolutely no problem... Oh, by the way, remember to close the door when you go out later."

Neville shook his head: "Professor, I'm not talking about whether it is stable or not, but whether this thing can really be used on people? I remember that the last time you used it was to make magic cloth."

"Theoretically, the enchantment table cannot be used either... No." Kaisen accidentally changed his words: "I said that this thing is theoretically the same as the enchantment table, it can be used on objects and on the human body, you can leave now, remember to close the door."

"Okay then." Neville nodded and walked towards the door, until he came to a huge machine, he quickly hid behind the machine, and quietly looked at the magic infusion table in the distance through the glass cover.

In case of danger, he could send Professor Kaisen to the medical wing as quickly as possible.

On the other side, Kaisen took out his staff and tapped the top cube.

Almost instantly, the gap of the cube burst into a blue light, and then the elements in the element jars surrounding the magic infusion table were also captured by the magic of the magic infusion table.

The wind element and speed element in the element jar were attracted to the cube and merged into the flying element.

At the same time, the wind attribute fragments on the surrounding tables began to melt and disappeared directly on the spot.

Bang!

Neville was shocked and rode on the broom directly, starting the speed of the light wheel 2000, and flew straight towards the magic infusion table like the last dive of the ball seeker.

Almost in just a moment, he came to the old site of the magic infusion table that had exploded into ruins. There was nothing left except those black building debris.

"Professor Kaysen... is dead?"

Neville's face wrinkled almost instantly, and he was about to fall off the flying broom.

"I personally suggest that if you ride a flying broom, it's better to choose a broom that is not so fast. To be honest, you can't think of riding a light wheel at full speed in the office."

Hearing this voice that sounded like comfort and ridicule, Neville covered his face and shook his head: "The professor is dead... huh?"

He turned around and saw Kaysen sitting cross-legged in the air, one hand on his knees to support his face, and the other hand holding the back of his collar.

"Professor... Professor? You can fly?"

"What else do you think I was doing just now? And what's so strange about this? Besides, how much do you despise me that you actually think I will die in such a small magic experiment?"

Kaysen smiled and lifted Neville's collar and put it on the ground.

"I mean, Professor, you... you are too... I am..."

"Forget it, if you can't say it, then don't say it."

Waving his hand, he indicated to Neville that he was fine, and he could go back to the dormitory to sleep peacefully.

And he had to repair the exploded magic infusion table, his poor glass floor, candles, and the elemental jars around him.

These were all his overtime work tonight.

And tomorrow he had to get up early and take Neville to Diagon Alley to buy a gift for Hermione.

"This is damn fulfilling."

The next day.........

"Professor, am I not late?" Neville appeared at the door of the alchemy office early with a bag of breakfast.

"Have you eaten?" Kaisen opened the door and looked at Neville carrying a bag of breakfast and asked this human-machine question.

"... I have eaten."

"Oh, come in."

Kasen took the breakfast very naturally and ate it in the seat in the office area.

On the other side, Neville was calculating his remaining pocket money.

This time he went to Diagon Alley not only to buy a gift for Hermione, but also to buy himself a flying broom.

It was somewhat inappropriate to always borrow Harry's flying broom for such a long time, and Quidditch training became more frequent as the Quidditch game approached, so he was embarrassed to borrow it from Harry.

"Are we leaving now?"

Soon, Neville saw that Kaysen had finished breakfast and put on his coat and asked.

"Go earlier. Otherwise, I will get up so early for nothing."

It was approaching October, and the temperature in England had begun to drop significantly.

In addition to the coat, the two of them also put on a layer of windproof wizard robes in detail.

"Professor, I don't understand why we don't use the Floo network of the fireplace."

"I accidentally broke the Floo network when I was renovating my office. I really don't like those guys in the Ministry of Magic, so I haven't asked anyone to repair it..."

"Of course, if you want to let Professor McGonagall know that you violated school rules and sneaked out on Saturday and then deduct five or six points, I would be happy to accompany you to borrow Professor McGonagall's fireplace."

"No, no, flying is fine."

The two of them pulled the drawstrings on their wizard robes as tight as possible, and Neville put on non-slip gloves and held the broomstick handle of the flying broomstick tightly.

"Let's go." Kaisen took off and flew directly through the hollow window on the French window. Neville also followed suit and carefully rubbed out.

Soon, the two walked out of a pet shop in Diagon Alley.

"This cat....is not good-looking either. Look at this face. At first glance, it looks like it has been hit by an anvil."

Kaysen looked down at the big-faced cat quietly nestling in the cage.

And the big-faced cat lazily raised his eyelids and looked at Kaisen, then moved his head directly, as if he was too lazy to answer Kaisen's impolite question, and directly refused to communicate.

"Well...if she doesn't like it, I can take him home and let my grandmother help raise him...but I think Hermione should like it. I remember that she likes small things with unique looks."

"Looks unique?" Kaisen touched his chin and looked up at the sky, but his eyes were secretly looking at the big-faced cat in the cage.

"It's very unique."

Soon, the two walked towards the broom shop again. Although the Longbottom family is not short of money, Neville, a second-year wizard, naturally cannot afford the full price of a high-end alchemical item like a motorcycle like a flying broom.

The only choice is to buy a second-hand one.

"Well... I found a new subject for you to learn." Kaisen walked out of the second-hand broom shop and looked at the Sweeping Seven Stars in Neville's hand. Suddenly, a light bulb appeared at a 45-degree angle upward in his head.
